ASX ANNOUNCEMENT 22 July 2016
West Melton Copper
Drilling Results Received
Marmota Energy Limited (ASX: MEU) ("Marmota")
KEY POINTS
-
In April/May 2016, Marmota tested 4 new target areas outside of the Champion prospect, to test for additional copper mineralisation in the area surrounding the Champion prospect, on the West Melton tenement on the Yorke Peninsula.
-
Targets were separate geophysical, geochemical and geological targets
-
24 RC holes were drilled over the 4 new copper targets
-
Best results obtained were associated with the geochemical target (copper-in- calcrete anomaly)
-
Results support Marmota's future focus and priority of working inside the Champion prospect (see ASX:MEU 16 June 2016, and the detailed report of Dr Kevin Wills on Champion itself)
Background
-
Marmota has a 100% interest in West Melton (EL 4648) [ see Fig. 1 ]
-
Drilling was conducted over 4 targets on West Melton from 23 April 2016 to 6 May 2016 with 24 slim-lined RC holes for a total of 1,268 metres
[ see ASX Release: 21 April 2016 ]
The 4 target areas were [ see Figures 1 and 2 ]:
-
Target 1: Copper-in-calcrete anomaly (holes WMAC30-38)
-
Target 2: TEM geophysical anomaly, NE extension from Champion (holes WMAC39 and 48-52)
-
Target 3: TEM geophysical anomaly (hole WMAC53)
-
Target 4: Structural/geological (holes WMAC40-47)

2016 West Melton Drilling Program Results
Assay results from the West Melton drilling program have been received.
No potentially economic mineralisation was intersected. No copper mineralisation was intersected at Targets 2-4.
Weak copper mineralisation was intersected at Target 1 confirming the effectiveness of copper-in-calcrete anomalies analogous to the Champion Prospect [ see Fig. 3 ]. [ The Champion prospect was discovered via testing copper-in- calcrete anomalies. ]
Of particular note in Target 4 and Target 1 was the following: Target 4
There was slightly elevated copper (up to 270 ppm) in hole WMAC045 and WMAC047 recorded where an inferred fault was intersected. No other holes in Target 4 intersected elevated copper values. Anomalous arsenic correlated with elevated copper results and to a lesser degree with silver.
Target 1: Geochemical copper-in-calcrete target
Target 1 was a geochemical copper-in-calcrete target. The drilling of Target 1 confirmed the surface calcrete geochemical anomaly overlies weak coincident copper supergene anomalism which was intersected in the drill holes. Although sub-economic, this result gives confidence to the surficial calcrete geochemical signatures and their ability to find mineralisation at depth in this region analogous to the Champion Prospect.
The supergene anomalism is coincident with moderately weathered, weakly oxidised metasediments. Weak underlying primary copper mineralisation in fresher schist is also seen at the end of hole in WMAC034. Silver and arsenic levels were marginally anomalous in holes with supergene copper mineralisation.
